Hey all,
Newly registered member here. I just successfully applied the update on my rooted Fascinate. The update failed the first time because I forgot to restore some of the system/apps files to their original names. After renaming the files, I tried the update again and it worked fine. Unfortunately, I lost root in the process. I didn't notice that at first because Root Explorer was able to go into the file system, but when I tried to rename the Bing file, it wouldn't let me. Will see how re-rooting goes. GPS is not any faster, but works okay. My favorite new feature is the HQ button on Youtube. No more going into the menu to watch HQ video when not on wi-fi.
